Experts, how is the furnace temperature of a converter calculated? Is there a formula?
You are referring to the temperature rise in the shift converter, right? According to the shift reaction equation CO + H2O = CO2 + H2 – 41.19 kJ/mol, the total heat released by the reaction is calculated based on the rate of change of CO. The specific heat capacity of the gas mixture is then looked up in a table, and after deducting approximately 5% for heat losses in the shift converter, the temperature rise at the inlet and outlet can be determined.
The heat of reaction for the conversion process can be calculated manually: it is necessary to know the constant-pressure heat capacity coefficients of each component in the mixture, as well as the heat effect of the conversion reaction under standard conditions, which is 41.154 kJ/mol. 1. The enthalpy change H1 occurs when the gases involved in the conversion are cooled from their current temperature to 25 degrees. 2. The enthalpy change H2 corresponds to the amount of CO that has been converted. 3. The enthalpy change H3 occurs when the gases after conversion are heated to a certain temperature T. For an adiabatic reaction, the value of T at which H1 + H2 + H3 = 0 is the temperature of the conversion furnace.
